BURNER PORT BLOCK ASSEMBLY

摘要

A burner port block assembly having a refractory block with a central passageway therethrough and a ceramic extension piece disposed at least partially in the central passageway of the refractory block. The extension piece has a distal end, a proximal end, and a sidewall that defines a central passageway extending between the distal end and the proximal end. The central passageway of the refractory block is provided with a first engagement structure and the sidewall of the extension piece is provided with a second engagement structure. Engagement of the first engagement structure with the second engagement structure connects the extension piece to the refractory block. The burner port block assembly may further include at least one ceramic fiber board having a hole therethrough disposed at the distal end of the refractory block and/or a gasket positioned between the refractory block and the extension piece.
